I had my wheels on and off more times than I care to remember.

Some points from an old guy:
1. Use a torque wrench (if you don't own a couple of torque wrenches your not doing it right)
2. Always wind the nut in by hand, never start with the impact driver, ugga dugga will kill em quick if the thread hasn't been started correctly.
3. I personally use the tiniest dab of anti-seize (50% of the internet will explode from this statement)
4. Always use closed nuts, open ended nuts will let contamination into the threads.
5. Cheap aluminium nuts are rubbish, use steel, or, if you need bling, Ti or Chromium-molybdenium steel like project Mu with floating seats.

Or, break them because monkey fisted, and then blame the product.

Or, just say they are rubbish in order to justify the purchase of some "brand name" studs in order to gain more "Bro" points to impress all the teenage boys.......
